摘　　要：目的确定妇女月经周期的个体内变异是否具有随机性。方法收集157名18-23岁女性大学生的连续月经周期数据(9-16个/人),用游程检验方法确定序列数据是否具有随机性。结果不超过5名学生的周期序列不具有随机性。结论妇女月经周期的个体内变异基本上是随机的;换言之,从某人某次的月经周期难以准确预测其下次月经周期的升降(相对于其周期均值或中位数而言)。Objective To determine whether the within-woman variation of menstrual cycles is random. Methods Consecutive menstrual cycles （9-16/person） were collected from 157 female college students aged 18-23 years, and the runs test was used to determine if the sequential data set was from a random process.Results Randomness was not detected in the data sets from no more than 5 students. Conclusion The intra-individual variation of women＇s menstrual cycles was essentially random; in other words, it could not be precisely predicted, from a cycle of a woman, whether her next cycle would increase or decrease （relative to the mean or median of her cycles）.
